    Fix Fortran/openmp: Partial OpenMP 5.2 doacross
    
    This removed a checking snippet which accidentally was left in in commit
    r13-2446-g938cda536019cd6a1bc0dd2346381185b420bbf8 ; this caused
    fails in gfortran.dg/gomp/doacross-5.f90 (added in that very commit).
    Note that a similar but refined check is now done in the middle end.
    (The ME version additionally checks whether doacross is present.)
    
    gcc/fortran/
            * openmp.cc (resolve_omp_clauses): Remove ordered/linear
            check as it is handled now in the middle end.
    
    (cherry picked from commit d6582c662ca0da05c74fa3183e1bc2cadcb21424)
